What would be a very conservative all inclusive US or EUR maintenance amount (in a high maintenance care scenario including winterisation/unwinterisation costs) to provision yearly on an 06/07/08 SAN210TE with about 200 hrs, based on 50 hrs yearly utilisation?

Hi Emanuel what you are asking is the cost of ownership. That, my freind is a lot of variables. Just insurance and storage could vary 25% region to region.
Maybe it's like the old saying:
"if you have to ask..."

You asked for maintenance costs, are you only looking for maintenance specifically or all anual costs associated with the boat? If you are interested in a complete anual cost I think we should start with a complete list of yearly costs, here is what I can think of.

Maintenance-~$500-$1500 for do it yourselfers and ~$1000-3000 for shop to do everything
Insurance~$300-$600
Registration (boat and trailer)~$50
Storage~$0 store at home-$2000 anual boatel
Marriage Counseling~$?

Aaron = Dealer maintenance
George = maintenance cost + winterisation & unwinterization (not inclusive of storage).
I am trying to gauge how much maintenance $$ I will roughly spend on this boat on a per year average (50 hrs of utilisation, 3 years).
Not married, so no counselling costs !! cheers!

Where you live will also have something to do with it. In Texas the off season is much shorter, so I do not mess with fogging the engine or adding anti-freeze. I simply drain my block/manifolds and add Sta-Bil to the gas tank before putting her up for the winter. When Spring rolls around I change the fluids and impeller. I also change the oil every 50 hours.

So unless something out of the ordinary pops up (bent prop, strut, rudder, shaft packing, etc) maintenance costs me about $100 per year. However, last season I tore up two props and a rudder. The rudder cost me about $250 (installed it myself) and the props were each $110 to have re-conditioned.

There are other expenditures that may or may not apply to you depending on where/how you store your boat. I keep mine in my backyard, so I do not have any storage fees. However, I do need to drop $400-$500 on a new cover every 3-4 years.
